24 papers that built AI
From Turing's 1950 question "Can machines think?" to the AI agents of 2025 — the complete story of how large language models came to exist, told through the papers that made it happen. Each paper is explained from first principles.
Group 1: The Foundations
1950–1997The paper that started it all. Alan Turing asked a deceptively simple question — can machines think? — and in trying to answer it, invented the entire framework through which we still think about artificial intelligence today.
Turing asked if machines could think. Rosenblatt built one that could learn. The Perceptron is the grandfather of every neural network alive today — the first machine that adjusted itself based on experience, rather than following rules someone wrote by hand.
The Perceptron could learn, but only simple patterns. Multi-layer networks could learn complex patterns, but nobody knew how to train them. This paper answered that question — with a single elegant algorithm that is still the beating heart of every neural network trained today.

Paper 08 — Attention Is All You Need — is the most important paper on this site. Everything modern AI is built on it. Start there.
